Basics of Floor Machine Brush Selection:

Do you want a brush or a pad driver?

If your preference is to have a dedicated product, select a brush. If you have a variety of applications, your choice may be a pad holder. The surface being cleaned and the amount of dirt build-up will help determine the selection. The key to remember when ordering these items is the block diameter in relationship to the machine size. A brush is sized 2 inches smaller than the machine because of the flare of the brush fibers. Pad drivers are specified 1 inch smaller than the machine.

There is an easy way to cross check your selection from the Floor Machine Brushes and Clutch Plates section of this web site.

A brush, long-trim pad driver, or short-trim pad driver without a riser, should be 2" smaller than the machine size.

A pad driver or MIGHTY-LOK™ should be 1" smaller than the machine size.

Therefore, a 20" floor machine would use an:

18" brush, MAL-LOK™ or PAD-LOK™ without a riser

or a 19" PAD-LOK™ or MIGHTY-LOK™

This rule applies to over 90% of the applications.

Determining Diameters

Block Diameter: Lay the brush on the bristles, block side up. Measure the actual outside diameter of the block (not the bristle flare). See photo below for reference (measurement B).

Once the correct size of brush and the proper clutch plate is determined, a few questions will enable you to select the correct type of brush or pad driver that is needed to fill your needs.

NOTE: Malish brushes are designed to fit each machine as shown, even though the block diameter listed on the charts may vary slightly from the diameter of the block originally supplied with the machine.

What is the make and model number of the machine?

When you have this information, please proceed to the Manufacturer/Brand Specific Equipment Reference List section of this web site. The machine manufacturers are listed in alphabetical order. Once your brand of machine is found, continue down until you find the correct model. By reading across, you can then determine the proper brush or pad driver size as well as the correct clutch plate.

When calling customer service toll FREE at 1-888-226-2724, please have the machine manufacturer and model number to help determine the block size, center hole diameter and clutch plate necessary to attach the block to the machine. If the machine size is not apparent from the model number, please provide this specification.

How to Break in a Brush

Before using a new brush on carpeting, the brush should be broken in according to the following directions. This will eliminate possible excess drag by “tipping” the strands, removing any possible burrs caused by the manufacturing process.

Break-in Procedure

Mount the brush on the floor machine. Follow ALL instructions included in your owner's manual.

Find a rough textured floor surface, preferably unfinished concrete.

Operate the machine on this surface. Run the machine DRY for approximately 15-20 minutes. The brush fibers will take a slight set or lean in the direction of machine rotation.

Rinse the brush to remove any dirt caught when running machine. The brush is now ready to be used on carpeting.
